urllib.request 里面的 urlopen proxies={‘http’:proxies} 无法识别出现下列错误如何解决

got an unexpected keyword argument 'proxies'

首先通过 cmd，用命令 python -v

找到 C:\Users\computorname\AppData\Local\Programs\Python\Python35\lib

这个位置就是 python的源码函数类库的存储位置

用sublime或其他编辑器查找上面的文件夹，查找内容为 def urlopen

发现上面 test/testurllib.py里面有 proxies关键字

就导入这个类库即可 from test.test_urllib import urlopen

from contextlib import closing
# from urllib.request import urlopen
from test.test_urllib import urlopen
# import urllib
# import requests
proxyConfig="http://%s:%s@%s"%("username","password","10.110.4.235:8080")
print(proxyConfig)
with closing(urlopen("https://www.python.org",proxies={'http':proxyconfig})) as page:
for line in page:
print(line)
